Position Overview:

This opportunity focuses on developing autonomous AI systems capable of reasoning, planning, and executing multi-step tasks with minimal human intervention. The engineer will build intelligent AI agents, integrate Large Language Models (LLMs), and develop agent-based workflows that interact with enterprise applications, APIs, and external data sources.

Specialized Technical Skills:

Strong programming experience with Python and object-oriented development.

Hands-on experience building AI agents using LangChain and LangGraph.

Knowledge of multi-agent frameworks such as CrewAI, AutoGen, or Semantic Kernel.

Experience with Large Language Models (LLMs) such as GPT, Claude, or Llama.

Strong understanding of Retrieval-Augmented Generation (RAG) and vector databases.

Experience with prompt engineering, tool calling, and function calling.

Knowledge of agent planning, reasoning, memory, and orchestration.

Experience integrating REST APIs, enterprise systems, and external tools.

Familiarity with vector databases such as Pinecone, Weaviate, or Chroma.

Exposure to AWS Bedrock, Azure AI Foundry, or Google Vertex AI.

Design and develop autonomous AI agents for enterprise business applications.

Build multi-agent workflows for complex task execution and decision-making.

Integrate LLMs with APIs, databases, and external enterprise tools.

Develop RAG-based applications to improve contextual information retrieval.

Implement agent memory, planning, reasoning, and orchestration mechanisms.

Build evaluation frameworks to measure agent accuracy and reliability.

Optimize prompts, model responses, latency, and token consumption.

Implement monitoring, logging, and security controls for AI agent systems.

Collaborate with data scientists, software engineers, and solution architects.

Maintain technical documentation and support production deployments.

Required Professional Experience:

5–8 years of experience in software engineering, AI, or machine learning.

2+ years of hands-on experience with LLM-based application development.

Practical experience developing AI agents and multi-agent systems.

Strong Python programming and API integration experience.

Experience implementing RAG pipelines and vector search solutions.

Knowledge of cloud-based AI services and deployment environments.

Understanding of AI safety, responsible AI, and application security.

Experience taking AI prototypes into production environments.

Academic Qualifications & Industry Certifications:

Bachelor's degree in Computer Science, Artificial Intelligence, Software Engineering, or a related technical field.

Master's degree in Machine Learning, Computational Linguistics, or Data Science is an added advantage.

Certifications in AWS Generative AI, Microsoft Azure AI, or Google Cloud Generative AI are preferred.

Practical project experience with autonomous agents, LLM orchestration, and intelligent automation is highly valued.
